奥龙HR-150DTⅡ型电动洛氏硬度计

HR-150DTⅡ电动洛氏硬度计

HR-150DTⅡ型电动洛氏硬度计选用全进口LCD数显表，代替了指针式表盘，消除了读数和操作误差，提高了显示精度和重复性精度，该机外观新颖，操作方便。适。采用自动加卸试验力机构，装有可调总试验力保持时间的电位器，试验力变换由变荷手轮的旋转而获得，所以操作简便迅速，除度盘对零外，没有人为的操作误差，具有很高的灵敏度，稳定性，适用于车间和实验室。

原理

    洛氏硬度适用于各种金属材料的硬度测定。它的试验原理是在初试验力及总试验力先后作用下，将压头压入试样表面，卸除主试验力，测量保留初试验力时的压痕残余深度。

技术参数：

初试验力：98.07N，允差±2.0%

总试验力：588.4N、980.7N、1471N，允差±1.0%

压头规格：金刚石圆锥洛氏压头、φ1.5875mm球压头            

被测试件允许最大高度：170mm

压头中心到机身距离：165mm

硬度计外形尺寸（长×宽×高）510×212×700m

仪器重量约：85kg

Product Name: HR-150DT Ⅱ Motorized Rockwell hardness 

Model: HR-150DT Ⅱ 

Details: HR-150DTⅡ Motorized Rockwell hardness selection all imported LCD digital display, instead of the dial pointer, eliminating the reading and operating errors and improve the accuracy and repeatability of the display, the aircraft the appearance of new, easy to operate. Fitness. Automatic unloading test force agencies, equipped with a total test force dwell time adjustable potentiometer, rotary converters test force transformation by the Dutch handwheel obtained, so easy to operate quickly, in addition to the dial to zero, there is no human operator error, with high sensitivity, stability, suitable for workshops and laboratories.

Principle:

Rockwell hardness measurement applies to all kinds of metal materials. Its principle is at the beginning of trial test force and total test force has the role of the indenter into the surface of the sample, removable main test force, measuring the depth of the indentation residual reserves at the beginning of the test force.

Technical parameters:

Preliminary test force: 98.07N, tolerance ± 2.0% 

Total test force: 588.4N, 980.7N, 1471N, tolerance ± 1.0% 

Head Specifications: 

Rockwell diamond cone indenter 

φ1.5875mm ball indenter            Be allowed to test the maximum height: 170mm 

Indenter center to the fuselage: 165mm 

Hardness Dimensions (L × W × H) 510 × 212 × 700m 

Instrument weight about: 85kg
